Description

[0001]
[Industrial application fields]
  In the present invention, when the liquid crystal display (LCD) panel and the driving TCP are finally pressure-bonded via an anisotropic conductive film, or when the anisotropic conductive film is temporarily pressure-bonded to the LCD panel side or the driving TCP side, the anisotropic conductive film is used. The present invention relates to an anisotropic conductive film crimping apparatus that uses a release film so that resin protruding from the film does not adhere to the crimping head.
[0002]
[Prior art]
  Conventionally, when connecting an electrode such as ITO of an LCD panel and an electrode circuit of a driving TCP, a method of connecting with an anisotropic conductive film (ACF) is generally widely used.
[0003]
  For this connection, a special-purpose crimping device is used. In such a crimping device, when the ACF is temporarily crimped to the LCD panel or TCP, the LCD and TCP are crimped together via the ACF and electrically connected. When connecting, a release film is used to prevent the protrusion of the ACF resin from adhering to the pressure-bonding head. In general, a Teflon sheet (Teflon is a registered trademark of EI DuPont de Nemours and Company) is widely used as a release film.
[0004]
  Such a crimping device has a crimper (crimping head) corresponding to the width of the ACF tape used for the connecting portion, and the tip shape varies depending on the application, but a plurality of TCPs are collectively crimped. In this case, for example, a slender head is used such that the size of the tip surface of the head to be bonded is 3 mm × 320 mm. The pressure-bonding head can be temperature-controlled, and can be heated as necessary. As a heating method, there are generally used a constant heating method in which a heater is connected to a temperature controller to control power by turning on and off, and a pulse heat method in which heat is generated in a short time. is there. The ACF is placed at a predetermined position on the LCD side or TCP side, and is temporarily crimped by a crimping head. At this time, silicon rubber or the like may be used as a cushioning material mainly for the purpose of uniform pressure bonding, or through a release film such as a Teflon sheet (Teflon is a registered trademark of EI DuPont de Nemours and Company). In some cases. Note that the ACF separator is peeled off after the temporary pressure bonding.
[0005]
  The LCD panel and the TCP are preliminarily aligned with the connection circuit, and as a means thereof, there is a case where the operation is performed by an operator using a microscope or a dedicated alignment device is used. In this way, the head is temporarily fixed through the ACF, and then the head is pressed against the connecting portion, or the head is pressed through silicon rubber or the like mainly for the purpose of uniform pressing, or the ACF is bonded In order to prevent the adhesive resin from sticking to the head, or silicon rubber, it is usually pressed through a release film that has a releasability for a predetermined time so as to reach a predetermined pressure, The main pressure bonding is performed. At this time, the ACF adhesive resin flows by heating and pressurizing, and those using a thermosetting resin are reacted and cured by heat to be bonded. On the other hand, the conductive particles in the ACF are crushed and an electrical connection between the LCD and TCP circuits is made.
[0006]
  As described above, the ACF temporary and final pressure bonding uses a releasable sheet. Currently, as described above, a Teflon sheet (Teflon is registered by EI DuPont de Nemours and Company). (Trademark) is widely used.
[0007]
  As a method of using this release film, conventionally, a release film cut to an appropriate size is placed on a connecting portion and a crimping operation is performed.
[0008]
  In addition, as shown in Japanese Patent Laid-Open No. 04-106881, a winding means for winding the release tape is provided on one of a pair of holders that hold the release tape on the pressure-bonding surface of the pressure head, and the other is provided on the other. By providing a tension applying means for applying a tension, a method of preventing forgetting to set the release film and occurrence of defects due to wrinkles of the release tape is performed.
[0009]
[Problems to be solved by the invention]
  However, the method of cutting the release film into an appropriate size and subjecting it to pressure bonding has the following problems.
(1) Since the release film is cut larger than the product, it can be wasted.
(2) Since the release film is wrinkled when it is pressure-bonded, the position of the release film must be set slightly shifted at the time of the next pressure-bonding, and work must be done so that the wrinkle is not pressure-bonded. In addition, if the product is crimped with wrinkles, the product will be defective.
(3) Since the release film is set manually by the operator, there is a risk of forgetting to set.
[0010]
  Further, the method of using a tape-shaped release film using the winding means and the tension applying means disclosed in Japanese Patent Application Laid-Open No. 04-106881 has the following problems.
(1) In order to attach an unused release film portion to a pressure-bonding head when winding and supplying a tape-shaped release film after product pressure bonding by a pressure bonding device, for example, a head having a total head length of 3 × 320 is 320 mm. The above must be unwound and used. For this reason, since this work is performed manually by the operator, it takes several seconds to several tens of seconds depending on the skill level. Sometimes, the unwinding of the release film and the mounting work on the head have the above-mentioned appropriate size. In the case of using a cut release sheet, it may be longer than the time required until the next pressure bonding is started.
[0011]
  Also, even if the tape release film mounting time is equivalent to the method of placing a cut sheet, the part used for pressure bonding and the unused part are used to unwind the entire length of the head, for example 320 mm, for the next pressure bonding. Therefore, it is necessary to determine the unwinding dimensions each time, and at least several seconds are required to wind up the 320 mm length.
[0012]
  As described above, it takes a certain amount of time to manually determine the unwinding dimension of the tape-shaped release film and to supply and mount it, and in the liquid crystal panel mounting process where productivity in one day is important Therefore, shortening the tact time is an important issue, and shortening the work for attaching the release film is an issue.
(2) The width dimension of the crimping head, for example, a release film with a width of 8 to 10 mm for a width of 3 mm, generally a tape-shaped release film must be prepared. This processing time is required, and the cost is increased by the processing cost.
(3) The width dimension of the crimping head For example, a release film of 8 to 10 mm width is used for crimping against a width of 3 mm, so the amount of the release film not used for crimping is based on the width dimension ratio of the head and tape. It is calculated to be about 63 to 70%, and it is thrown away unused.
(4) It is difficult to process a roll of a tape-shaped release film having a width of 8 to 10 mm as a long product such as a roll of 100 m or 300 m, and to produce a roll that is correctly wound without becoming a bamboo shoot. Further, in the method in which such a long tape-shaped release film is mounted on the holding metal fitting and the pressure bonding head disclosed in Japanese Patent Laid-Open No. 4-106891, the size of the long tape-shaped release film is too large. I can't. Furthermore, since the weight of the tape-shaped release film acts on the pressure-bonding head, the influence on the pressure-bonding force cannot be ignored.
[0013]
  For this reason, the maximum length of the tape-shaped release film is limited, but if the release film is used up while the crimping operation is proceeding, the tape-shaped release film is set on the holding bracket again. It must be done and time is spent on this setup.
[0014]
  Therefore, the present invention has been made paying attention to such a problem, and can greatly reduce the working time and setup time, and can save a release film and can easily use a long product. An object is to provide a conductive film crimping apparatus.
[0015]
[Means for Solving the Problems]
  In order to achieve the above object, according to the first aspect of the present invention, when the LCD panel and the driving TCP are permanently pressure-bonded via an anisotropic conductive film, or the anisotropic conductive film is temporarily attached to the LCD panel side or the driving TCP side.

Do. The supply means supplies the release film to the pressure bonding means in conjunction with the end of the main pressure bonding operation or the temporary pressure bonding operation by the pressure bonding means.Further, when the supply means supplies the release film to the pressure bonding means, the control circuit is interlocked with the end of the main pressure bonding operation or the temporary pressure bonding operation by the pressure bonding means.

And control to apply tension to the spring of the tension shaft.
[0018]
  According to a second aspect of the present invention, the supply means finishes the final crimping operation by the crimping means or temporarily presses it.ArrivalIn conjunction with the completion of the operation, the release film is supplied to the crimping means by a length corresponding to the width dimension of the crimping head of the crimping means.
[0019]
【Example】
  Examples of the anisotropic conductive film crimping apparatus according to the present invention will be described below.
[0020]
  FIG. 1 shows the configuration of the anisotropic conductive film crimping apparatus of this embodiment.
[0021]
  In this apparatus, the driving TCP is pressure-bonded to the LCD panel 4 through an anisotropic conductive film (ACF) 6 while winding the release film 1. The pressure-bonding head 2, the silicon rubber 3, the cradle 7, , Unwinding shaft 8, electromagnetic brake (MB) 9, torque limiter (TL) 10, microswitches 11 and 12, dog 13, stopper fitting 14, tension shaft 15, spring 16, and fixed shaft 17. And guide rolls 18 and 19, a winding shaft 20, a winding motor 21, and a control circuit 40.
[0022]
  The unwinding shaft 8 can be appropriately set and switched between a movable state and a fixed state by an electromagnetic brake 9. The unwinding shaft 8 in a movable state is given an appropriate resistance force, that is, unwinding torque so as not to slip. This torque force is such that when the release film 1 in a wound state is unwound, the unwinding shaft 8 does not rotate too much due to its inertial force, and when the tension shaft 15 is pulled back to a predetermined position. The tension of the spring 16 is set to a value smaller than the torque force when acting on the release film 1.
[0023]
  Further, when the spring 16 of the tension shaft 15 is extended to the full movable range of the unwinding shaft 8 in the fixed state, the resistance torque is sufficiently larger than the torque generated at the maximum diameter of the release film 1 in the wound state. To take. That is, even if a pulling torque smaller than the resistance torque is applied to the unwinding shaft 8 for a long time, the unwinding shaft 8 does not rotate and the fixed state can be maintained.
[0024]
  As described above, the tension shaft 15 is connected to the spring 16 so as to be able to move back and forth, and the tension by the spring 16 changes depending on the movement position of the tension shaft 15. When the release film 1 is passed through the tension shaft 15, a tension that matches the tension of the tension shaft 15 is applied to the release film 1, so that the release film 1 is determined by determining the position of the tension shaft 15. 1 tension can be set.
[0025]
  Therefore, the tension is applied to the release film 1 by the electromagnetic brake 9, the tension of the tension shaft 15 by the spring 16, and the driving of the winding shaft 20.
[0026]
  Further, the torque limiter 10 is one that constantly maintains a constant resistance torque independently by an internal permanent magnet so that no sag occurs in the release film 1, and has a resistance torque of about 1 kgcm.
[0027]
  The microswitches 11 and 12 are used as position detecting means for controlling the tension shaft 15 to be in an appropriate position, and the stopper fitting 14 is for mechanically limiting the movement amount of the tension shaft 15. It is.
[0028]
  The take-up shaft 20 is arranged on the front side of the crimping apparatus and is driven by the output of the take-up motor 21 decelerated by a gear. The winding motor 21 is controlled by a control circuit.40It is configured so that it can be rotated normally and reversely with a manual switch so that it is performed by the internal sequence controller 22 and convenient for the sheet passing operation of the release film 1 or the like.
[0029]
  Next, attachment of the release film 1 to the apparatus will be described with reference to FIG.
[0030]
  In order to attach the release film 1, first, the release film 1 (for example, thickness 50 μm, width 500 mm) is attached to the unwinding shaft 8 and passed through the tension shaft 15 and the guide roll 18. Although not shown, an aluminum pipe having an outer diameter of 8 mm and a length of about 500 mm is wound around and temporarily fixed to the drawer end of the release film 1 using a double-sided tape.
[0031]
  Then, the center of the aluminum pipe is pulled with a spring balance to mark the position of the tension shaft 15 when a force of 500 gf is applied, the aluminum pipe is removed from the release film, and the winding shaft 20 is passed through the guide roll 19. To pass through.
[0032]
  Then, the position of the micro switch 12 for detecting the position of the tension shaft 15 is adjusted, and the position of the tension shaft 15 is fixed by the stopper fitting 14 so as to be the mark position. That is, the tension shaft 15 is abutted and fixed to the stopper fitting 14 so that the tension shaft 15 is positioned at the marked position, and a position where the microswitch 12 is just turned on is found in this state, and the microswitch is detected at that position. 12 is fixed.
[0033]
  Next, the unwinding feed amount of the release film 1 is set.
[0034]
  In principle, the unwinding amount of the release film 1 is about “2” with respect to the movement amount “1” of the tension shaft 15, and when the tension of the spring 16 that pulls the tension shaft 15 is “1”, the mold release is performed. The applied tension of the film 1 is approximately “½”. In the experiment, the stopper jig 14 is moved and attached so that the moving amount of the tension shaft 15 is 5 mm.
[0035]
  And the unwinding shaft 8 is unwound by the electromagnetic brake 9.8The torque is adjusted by the torque limiter 10 so that the release film 1 does not rotate too much due to inertial force and the release film 1 does not sag. .
[0036]
  FIG. 2 shows the configuration of the control circuit 40.
[0037]
  The control circuit 40 is configured to unwind the release film 1 from the unwinding shaft 8 by controlling the operations of the electromagnetic brake 9 and the winding motor 21 by the sequence controller 22.
[0038]
  That is, the control circuit 40 operates the relay 26 with the sequence output signal via the sequence controller 22, thereby operating the electromagnetic brake 9. In addition, since a back electromotive force is generated in the coil of the electromagnetic brake 9 when the power is turned off, a diode 28 is connected as a protective element so as to eliminate this.
[0039]
  Also, the operation control of the take-up motor 21 by the sequence controller 22 is such that when the micro switch 11 is turned on, the sequencer controller 22 operates the relay 24 to rotate the take-up motor 21 forward, and once the micro switch 11 is turned on. The winding motor 21 is controlled so as to continue to rotate even when turned off. On the other hand, when the microswitch 12 is turned on, the winding motor 21 is stopped. Further, a manual motor switch 27 is provided so that the take-up motor 21 can be manually rotated forward and backward arbitrarily.
[0040]
  In the figure, reference numerals 23, 24 and 26 denote relays, 25 denotes a brake switch, 29 denotes a DC power supply regulator, 30 denotes a circuit breaker, and 31 denotes a DC power supply.
[0041]
  Next, the operation of the apparatus configured as described above will be described with reference to the drawings.
[0042]
  First, the roll of the sheet-like release film 1 is attached to the unwinding shaft 8, and the paper passes through the tension shaft 15, the guide roll 18, and the lower portion of the pressure-bonding head 2 that is a pressure-bonding portion. It is wound up by a winding shaft 20 through a guide roll 19. At that time, the take-up shaft 20 is prevented from rotating by the brake.
[0043]
  When the winding motor 21 is rotated forward, the winding shaft 20 rotates, and the tension shaft 15 overcomes the tension of the spring 16 and is pulled by the release film 1. Move to the right side of the figure.
[0044]
  When the tension shaft 15 moves to a preset position, the microswitch 12 serving as a position detection sensor operates to output a signal. The sequence controller 22 receives this signal and stops the winding motor 21.
[0045]
  In this state, the strength of the spring 16 of the tension shaft 15 and the stop position of the tension shaft 15 are determined in advance so that the tension of the release film 1 becomes an appropriate value.
[0046]
  Then, when a new release film 1 is supplied to the pressure-bonding section, the pressure-bonding head 2 performs the main pressure bonding of the LCD panel 4 and the driving TCP 5 from above the release film 1 via the anisotropic conductive film 6, Alternatively, the anisotropic conductive film 6 is temporarily pressure-bonded to the LCD panel 4 side or the driving TCP 5 side.
[0047]
  Here, the sequence controller 22 supplies the release film 1 in conjunction with the completion of the final pressure bonding operation and the temporary pressure bonding operation after the main pressure bonding or the temporary pressure bonding is performed by the pressure bonding head 2. First, a command for releasing the brake to the electromagnetic brake 9 and setting the unwinding shaft 8 in a movable state is output. In addition, supply of the release film 1 shall be performed when malfunctions, such as a stain | pollution | contamination, etc. arise in the release film 1, or every fixed frequency | count of crimping | compression-bonding.
[0048]
  Then, the tension shaft 15 is moved to the left in the drawing by the tension of the spring 16, the unwinding shaft 8 is rotated, and the release film 1 is unwound. The amount of unwinding of the release film 1 is determined by the amount of movement that is pulled back by the spring 16 of the tension shaft 15. The unwinding amount of the film 1 is set.
[0049]
  Further, the micro switch 11 is operated as a position detection when the tension shaft 15 is pulled back to a predetermined position, and the micro switch 11 contacts the stopper fitting 14 with the tension shaft 15 pulled back. Or it is attached to the place where the sensor detects just before that.
[0050]
  The detection signal from the microswitch 11 is input to the sequence controller 22 in the control circuit 40.
[0051]
  The sequence controller 22 expects the time from when the sensor is detected by the program to when the tension shaft 15 comes into contact with the stopper fitting 14, and counts that time to delay by a certain time until the next operation instruction. To. After the predetermined delay time has elapsed, the sequence controller 22 outputs a signal for turning on the electromagnetic brake 9 of the unwinding shaft 8 so that the unwinding shaft 8 is fixed.
[0052]
  Next, the sequence controller 22 outputs a signal for normal rotation of the winding shaft 20 to the winding motor 21.
[0053]
  Then, the unwinding motor 21 rotates in the forward direction, the release film 1 is taken up, and a new release film 1 is supplied to the pressure-bonding portion. It overcomes the tension of the spring 16 and moves to the right in the figure.
[0054]
  When the tension shaft 15 moves to a preset position, the microswitch 12 serving as a position detection sensor operates to output a signal, and this signal is input to the sequence controller 22, and the sequence controller 22 21 is stopped.
[0055]
  Here, in this embodiment, the rotation time of the winding motor 21 when supplying the release film 1 in conjunction with the end of the crimping operation is limited to a predetermined time.
[0056]
  For example, when the release film 1 is cut, the tension shaft 15 does not move to a predetermined position no matter how much the winding motor 21 continues to rotate. Therefore, when the release film 1 is cut by setting the maximum rotation time of the winding motor 21 in the program of the sequence controller 22 and stopping the rotation of the winding motor 21 when this time has elapsed. Can be effectively dealt with.
[0057]
  Therefore, according to the present embodiment, the electromagnetic brake 9 and the take-up motor 21 are operated in conjunction with the completion of the operation of the main pressure bonding or the temporary pressure bonding using the release film 1 by the pressure bonding head 2, and the pressure bonding is performed. After completion, the release film 1 is automatically unwound and supplied while the table of the crimping device moves and proceeds to the next process, so the release film 1 is provided for crimping without relying on the operator. In addition, the setup time and work time can be greatly reduced as compared with the conventional manual supply method.
[0058]
  Further, since the release film 1 is automatically unwound from the unwinding shaft 8 by a necessary amount after completion of the pressure-bonding operation by the pressure-bonding head 2 and is always supplied with a tension applied by the tension shaft 15, Crimping can be performed so that the wrinkles of the release film 1 once generated by the previous crimping operation do not occur during the next crimping operation.
[0059]
  Moreover, since the release film 1 is in the form of a roll, it is not necessary to cut each piece and can be easily elongated. Further, since the release film 1 uses a wide roll, the width is 8 to 10 mm. Narrow onePreparationdo not have to.
[0060]
  Further, when the width dimension of the pressure bonding head 2 is, for example, 3 mm, it is possible to set the supply feed amount of the release film 1 after the pressure bonding to 6 mm. Locations that are not provided can be greatly reduced.
[0061]
  Furthermore, the set-up time for using the release film 1 by pressure bonding or the like and newly attaching it to the unwinding shaft 8 is comparable to the method using the holding metal fitting disclosed in Japanese Patent Application Laid-Open No. 04-106891, or in some cases Although it may take a long time, if the roll-off release film 1 is mounted on the unwinding shaft 8, it can be used for a considerable period of time, depending on the length of the roll. Among them, the setup time is shortened in total.
[0062]
【The invention's effect】
  As explained above, by using the release film supply device of the present invention,
1. When the release film has a problem such as dirt, or after a certain number of press-bonding operations, it is not necessary to manually calculate the unwinding dimensions and take-up work to unwind the release film. Since the release film is automatically supplied in conjunction with the completion, the setup time is greatly reduced.
2. Compared with the tape-like release film, a sheet-like release film may be prepared, so that the processing time for the width dimension can be reduced, and the processing cost is reduced.
[0063]
3. Since the sheet-like release film can be continuously supplied and the feeding amount can be arbitrarily set, the number of sheet portions that cannot be subjected to pressure bonding can be reduced as much as possible, and the cost of the expensive release film can be greatly reduced.
4). Since it is a sheet-like release film, a long product such as a 100 m roll or a 300 m roll can be easily manufactured by a manufacturer, so that the manufacturer can easily supply it.
5). The weight of the long release film does not affect the crimping.
6). Since long release film can be used continuously for crimping, it can be used for a considerable amount of time once the release film is passed through. Is planned.
